Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IP IH FC
c-erbB-2 is the cellular homolog of the neu oncogene. c-erbB-2 is comprised of an extracellular ligand binding domain, a single transmembrane domain, a tyrosine kinase domain, and a C terminal region which mediates signaling. c-erbB-2 forms heterodimers with other members of the EGF receptor family, such as c-erbB-1. In response to ligand binding, c-erbB-2 is autophosphorylated on five tyrosine residues at its C terminus, producing docking sites for SH2-domain containing proteins such as phospholipase C , PI3-K, Src, CHK, and others. Over-expression of c-erbB-2 is observed in 15-40% of primary human breast tumors, and correlates with poor prognosis in node positive breast cancer. c-erbB-2 over-expression is also observed in ovarian, gastric, salivary, and non-small cell lung carcinomas.
